1 minute and 52 seconds is equal to 112000ms (1minute * 60seconds/minute + 52seconds = 112seconds = 112seconds * 1000ms/seconds = 112000ms).
And since in the bookmark file you need to multiply every ms by 10000, the number you have to add to every line (to add 1 minute and 52 seconds at every bookmark) will be
1120000000
